To create Joomla categories, follow these steps:
1. Login to your Joomla backend.
2. Click on the “Content” menu item and go to “Categories”.
3. Click on the “New” button.
4. Enter a title for your new category.
5. Choose a parent category (if applicable) from the dropdown list.
6. Choose a category type. Joomla offers a few different types of categories, such as “Articles”, “Banners”, and “Contacts”.
7. Enter a description for your category (optional). This will help users understand what content belongs in this category.
8. Set the “Access”, “Language”, “Metadata”, and other options as desired.
9. Click on the “Save & Close” button to create your new category.
Repeat this process as many times as necessary to create all the categories you need.
